SYRINGE.

Specification of Letters Patent.

Patented Oct. "7, 1913.

Application filed March 17, 1913. Serial No. 754,825.

To all whom it may concern Be it known that I, JAMEs H. L. EAGER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Syringes, of which the following is a specification.

My invention relates to syringes, and more particularly to that class known as waterbag syringes and in which a pressure-seat is used which rests upon the bag, the weight of the person using the syringe causing the water or other cleansing fluid to be forced from such bag and through an injection nozzle to the part to be treated.

In the accompanying drawing illustrating the preferred embodiment of my invention, Figure 1 is a side elevation of my improved syringe, ready for use, Fig. 2 is a vertical section through the syringe nozzle and the support therefor, showing the means for attaching the water tube, and Fig. 8 is a fragmentay bottom plan view of the support for the nozzle, showing the means for attaching the water tube.

Like letters of reference indicate corresponding parts wherever they occur.

4 designates the usual form of water bag, made of rubber or rubber cloth having a screw threaded filling opening.

5 designates a pressure-seat adapted, as shown, to be placed upon the water bag and provided with a central opening 6 therethrough.

Seated upon the face of the pressure-seat and covering the central opening 6 is a domeshaped nozzle holder 7 provided interiorly with a screw-threaded portion 8, adapted to receive an injection nozzle 9, having the dis charge apertures 10 which nozzle is preferably formed from soft rubber. Such nozzle may, however, be of the hard rubber type, in which case its lower end is provided with a thread by which it is screwed into place to match that in the nozzle seat.

Extending from the bottom of the down wardly extending portion 8 of the nozzle support is a short pipe section 10, closed at its lower end, and provided with a screw threaded side opening 11, adapted to receive a similarly threaded nipple 12, the opposite end of which fits in the end of a rubber tubing 13, the other end of which tubing is provided with a screw threaded nozzle adapted to be screwed into the filling opening of the bag 4. The rubber tubing 13 intermediate its ends is provided with a metal cut-0E 14 of the usual construction for this purpose.

15 designates metal tubes, the ends of which are inserted in the rubber tubing and which form desirable connections at the joints of such rubber tubing.

As will be seen from the drawing the pressure-seat 5 is of such size relative to the side of the water bag 4 as to practically cover the same, so that the person of the user is prevented from coming in contact with the hot surface of such bag.

My improved syringe is particularly adapted for the treatment of the rectum and colon and for the flushing or irrigating of these parts, and in the particular use thereof the pressure-seat may be used as a handle in placing the injection nozzle in position for use, the water-bag having been previously filled with water or cleansing fluid and the screw threaded end of the rubber tubing attached thereto. The pressure-seat is then placed upon the bag, the patients weight thereon causing the water or other cleansing fluid to be gradually expelled from the bag and through the injection nozzle to the parts to be treated. The dome-base for the injection nozzle serves to press upward the rectum to prevent the escape of water therefrom, as well as a means for housing the water inlet from the rubber tubing, such tubing being covered for a portion of its length and extending under the base, resting in a groove 16 formed in said base, whereby to house the same and to permit an even or flush surface of the underside of the seat 5 on the bag 4, and thereby prevent rocking of said seat on said bag, and consequent wear of the latter.

While I have described my improved syringe as particularly adapted for the treatment of the rectum and colon, the same may be also used as a vaginal douche.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

A syringe comprising a water-bag, a pressure-seat consisting of a flat integral member of sulficient area relative to the side of the water-bag upon which it is adapted to be placed to shield the user from contact with the surface of said bag and having an opening therethrough, a dome-shaped nozzle support mounted on said seat over said opening and provided with a water-passage In testimony whereof I affix my signature therethrough adapted to receive an injector 1n presence of two wltnesses. nozzle, and a tube extending beneath said i 4 4 pressure-seat and connected at one end with JAMES DAGER" 5 the Water passage through said dome-shaped Witnesses:

nozzle support, and having its other end at- E. Col-ION, tached to the mouth of the Water-bag. L. A. PUTTS.
